Evaluate $3(x-7)+5$ when $x=9$ .

STEP 1

Assumptions
1. The expression to evaluate is $3(x-7)+5$ .
2. The value of $x$ is given as $9$ .

STEP 2

First, we substitute the given value of $x$ into the expression.
$3(x-7)+5 = 3(9-7)+5$

STEP 3

Next, we perform the operation inside the parentheses.
$3(9-7)+5 = 3(2)+5$

STEP 4

Now, we multiply the value outside the parentheses by the result inside the parentheses.
$3(2)+5 = 6+5$

STEP 5

Finally, we add the two numbers together to get the final result.
$6+5 = 11$
The evaluated expression $3(x-7)+5$ given $x=9$ is $11$ .
